Why isn't my machine recognizing changes?

I just got an Omtech 3655 Pro and I'm trying to figure it out. I had an Xtool d1 pro and a simple test like this would give me dramatically different results.

As you can see there is absolutely no difference in the lines from 100 mm/s to 1200 mm/s. Power settings don't make sense on the test either... I'm using lightburn.
